<p>Instance that wishes to support certain request protocol, just implement the corresponding

<p>Note:
Query handlers are not confined to only handle read requests, they are expecting to handle
write requests too. So the “query” here not might seem ambiguity. However, “query” has been
used as some kind of “convention”, it’s the “Q” in “SQL”. So we might better stick to the
word “query”.</p>
